Microscope and Telescope

Why are the magnification properties of microscopes and telescopes defined in terms of the ratio of angles and not in terms of the ratio of sizes of objects and images?

Explain the concept of resolving power. Briefly discuss resolving power of a microscope and a telescope.

How will you distinguish between a compound microscope and a telescope just by looking at them ?

$ The entire material world which can be seen and detected with instrument is like microscops and telescope is called universe. ! Living organisms are unevenly distributed in the biosphere

Consider the following statements about a microscope and a telescope 1. Both the eyepiece and the objective of a microscope are convex lenses. 2. The focal length of the objective of a telescope is lerger than the focal length of its eyepiece. 3. The magnification of a telescope increases with the increases in focal length of its objective. 4. The magnification of a microscope increases with the increases in focal length of its objective. Which of the statements given above are correct?

In which, microscope or telescope, the difference in the focal lengths of the two lenses is larger ?

Mention differences between light microscope and electron microscope.
